The vagina is the canal that leads from the outside of the body to the cervix , the opening to the uterus.

The uterus is the muscular organ where a fertilised egg, or embryo, attaches and develops. It is the size and shape of a pear and lined with a rich and nourishing membrane, the endometrium . The fallopian tubes extend from the top of the uterus down over the ovaries, the two walnut-sized organs that contain the eggs.
